0.1 The main components include a standard part of the safe operation of elevators affect larger parts, not including wearing parts, the use of new technologies In the elevator and the application of fewer components.

0.2 standard specifies the technical conditions of the elevator scrapped main components, unspecified judgment scrapped the program. After

0.3 floods, earthquakes, fires and other disasters, you may need to lift the overall safety assessment of the actual situation, determine its main components Scrapped technical conditions.

0.4 pairs of the quantitative criteria are not technical conditions, reference product maintenance manual.

0.5 elevator main parts scrapped achieve technical conditions specified in this standard, or reach retirement maintenance and technical conditions given in the specification, excellent Consider repair, such as after repair still does not meet the requirements or repair costs are too high to be considered scrapped. Elevator main parts scrapped technical conditions

1 Scope

China's national specification for when the main parts of a lift must be taken out of service - the document a maintenance company, an inspector and a building owner argue over, because the question it answers is the one that costs money: is this component still serviceable, or must it be replaced. It specifies the technical conditions for the discard of the main parts of lifts, and it applies to the maintenance, the inspection and the modernisation of lifts in service. The parts it covers are the ones on which the safety of the installation rests: the suspension ropes and belts, with the wire breaks, the loss of diameter, the corrosion and the deformation that condemn them; the traction sheave and the diverter pulleys, with the groove wear that lets a rope slip; the brake, its linings and its springs; the guide rails and the guide shoes; the safety gear and the overspeed governor; the buffers; the car and counterweight frames and their fixings; the doors and their locks and operators, which is where most lift accidents actually happen; and the controller and the electrical components. For each the standard sets the measurable criterion at which the part is to be discarded rather than adjusted or repaired, together with how the measurement is to be made. The value of writing that down is that it converts a judgement into a check: a lift that has been in service for twenty years is not condemned by its age, and a rope with a single broken wire is not condemned at all, but a rope past the limit in this standard is, and nobody has to argue about it. Issued on 3 July 2015 and in force since 1 February 2016.

This standard specifies the traction and positive drive elevator, hydraulic elevator main parts scrapped technical conditions. This standard applies to the rated speed of not more than 6.0m/s of traction electric drive type and rated speed not greater than 0.63m/s Power drive Fixed compulsory passenger elevators and lifts, and a rated speed of not more than 1.0m/s hydraulic lift. For the rated speed greater than 6.0m/s of Traction electric drive passenger lifts and service lifts execution may refer to this standard. This standard does not apply to lifts. Special circumstances (such as apply to disabled persons, fire, potentially explosive atmosphere, extreme climate conditions, seismic conditions or transport hazardous Articles, etc.) used in elevators, in addition to the requirements of this standard should be determined in accordance with the relevant standards and technical conditions scrapped additional requirements.

3 Terms and Definitions

GB/T 7024, GB 7588-2003 and GB 21240-2007 define the following terms and definitions apply to this document.

3.1 The main components mainparts The safe operation of the elevator components play an important role, for example. the host drive, suspension and the like.

Note. This standard covers only part of a greater impact on the safe operation of the elevator lift the main components.

3.2 Repair repair Parts damaged, degraded or functional failure, the replacement of parts, processing, repair and other measures taken by, to restore the original knot Structure and function.

3.3 Discard scrap Part because they can not continue to use or performance indicators do not meet the requirements and void.
